CY7C425-25PC

FIFOs Memory Overview

The CY7C425-25PC is an asynchronous FIFO manufactured by Cypress Semiconductor Corp. It features a memory organization of 1K x 9 bits, providing a total capacity of 9 kilobits. The device operates with a maximum access time of 25 nanoseconds and supports a clock frequency up to 28.57 MHz. It utilizes CMOS technology and is housed in a 28-pin Plastic Dual In-Line Package (PDIP) with a 0.300-inch body width. The component functions in asynchronous mode and includes retransmit capabilities.

FIFOs Memory Feature Summary

• Asynchronous operation for independent read and write clocks
• CMOS technology for low power consumption
• Retransmit capability for data integrity

FIFOs Memory Applications

• Data buffering between different clock domains
• Interface bridging in high-speed digital systems
• Temporary storage in communication protocols

FIFOs Memory Procurement Notes

Verify the specific suffix 'PC' against official Cypress documentation to confirm package type and temperature range. Ensure compliance with RoHS directives as indicated by the non-compliant status found in some records. Confirm availability through authorized distributors or secondary markets due to potential end-of-life status.

FIFOs Memory Selection Notes

Select this component when asynchronous FIFO functionality with 1K x 9 depth is required. The 25ns speed grade suits moderate-speed applications. Consider the PDIP-28 package constraints for PCB layout. Compare with other CY7C425 variants if different speeds or packages are needed.

FIFOs Memory Part Context

Part of the CY7C425 family of asynchronous FIFOs from Cypress. This family offers various depths and speeds. The CY7C425-25PC specifically denotes the 25ns speed grade in a PDIP package. Related parts include CY7C425-25PI and CY7C425-20PC.

FIFOs Memory Replacement Considerations

Check for direct substitutes within the CY7C425 series such as CY7C425-25PI for pin-compatible alternatives. Verify electrical specifications match exactly before substitution.
